1. GENERAL
This specification is general in nature and applicable as a reference to all applications and
not as a substitute for the equipment manufacturer's specifications and/or standards.
All threaded fasteners shall be tightened using a torque wrench in accordance to Table 1 and
in accordance with Appendix A — Bolting Patterns unless otherwise specified by the
equipment manufacturer.
2. MATERIAL
2.1. Threaded fasteners shall be in accordance with ASTM specifications A193 Grade
B7 and A194 Grade 2H.
2.2. The shortest bolt shall be used that permits full engagement of the thread through
the nut. A minimum of three threads shall protrude beyond the nut face after hand
tightening.
2.3. Use of salvaged bolts and nuts is prohibited.
2.4. Threaded fasteners may be reused in certain applications approved by Company's
Representative. Reused threaded fasteners must meet all of the following
requirements:
2.4.1. Fasteners are clean, free of corrosion, paint, thread damage, teeth marks
(such as caused by pipe wrenches) or other signs of damage.
2.4.2. Fasteners have not been used underwater or coated with coal tar products.
2.4.3. Fasteners have not been tightened to or beyond their yield strength. (This
condition can be determined by comparing the bolt threads of a used bolt to
those of a new bolt. The nut should be capable of being finger tightened
over the entire thread length.)
3. SURFACE PREPARATION
3.1. Threads, connecting, and seating surfaces shall be free of dirt, grit, paint, nicks and
metal shavings.
3.2. Sharp edges of a drilled hole shall be cleaned before placement of a fastener.

4. LUBRICATION
Lubricant, if required, shall be selected and applied in accordance with the equipment
manufacturer's recommendations. If no recommendations are available, Company's
Representative shall determine an approved lubricant.
5. GASKETS
5.1. New gaskets shall be used on all new construction and gaskets shall not be reused.
5.2. All damaged gaskets shall be replaced.
5.3. Anti -seize compounds shall not be used unless approved by the Company's
Representative.
6. TORQUE WRENCHES
6.1. All torque wrenches shall be properly calibrated to 2% of the full scale reading.
Torque wrenches shall be recalibrated after extensive use or at least every six
months. Contractor shall have calibration certification available for Company's
review.
6.2. Torque wrench selection and application shall be in accordance with the torque
wrench manufacturer's recommendations. Torque wrench selection shall have
adequate capacity so that the working range is within the mid -quarters of the scale.
6.3. Automatic torque tools shall have the set limits verified with a calibrated manual
torque wrench.
7. TORQUING
7.1. All fasteners shall be finger tightened, ensuring the bolt has full thread engagement
through the nut.
7.2. On multi -fastener applications, the torque shall be applied in a method that allows
the fasteners to be evenly and sequentially tightened, in gradual increments, to the
recommended torque value, as indicated on Table 1.
7.3. The torque shall be applied in a minimum of three equal applications following a
crisscross bolting pattern until the recommended torque value is attained at all the
fasteners. Reference the attached bolt pattern diagrams in Appendix A.

1.4. Weather Conditions and Dryness of Surface
1.4.1. Paint shall not be applied to any surface whose temperature is below 40°F,
or on surfaces whose temperature is less than 5°F above the dew point. If it
is suspected that temperature and humidity conditions are such that
moisture is condensing upon the surface, the surface shall be moistened
with a damp cloth to apply a clearly defined, thin film of water. If this thin
film of water evaporates or decreases in area after 15 minutes, the surface
shall be considered safe to paint from the standpoint of continued
condensation at that particular time.
1.4.2. Paint shall not be applied after a heavy frost or on extremely cold faces, nor
when there is a likelihood of change in weather conditions within two hours
after application which would result in a low air temperature or
accumulation of moisture in the form of rain, snow, condensation, etc.,
upon the surface.
1.4.3. The Company Representative shall have the authority to stop or disapprove
the application of paint when impending weather conditions may be
detrimental to application process.
1.5. Number of Coats
All metal or wood surfaces to be painted shall receive coats of primer and finish
coats of the type of paint or enamel specified on the Drawings, in the Scope of

of soft skins which might cling to brushes.
1.7. Thinning
Adjustment of paint consistency by thinning shall be done only in accordance with
the manufacturer's recommendation and only after obtaining specific permission
from the Company Representative_ The general rule for thinning paints shall be that
a full hiding coat can be applied without sags or runs, to thoroughly obscure the
surface being painted, whether bare metal or undercoat.
1.8. Brush Application
1.8.1. Brush application of paint shall be kept at a minimum. Application data
and procedures shown in the Company's Specifications shall be followed
and may be changed only with the approval of the Company
Representative. The primer coat shall be applied by spraying, except that
on small jobs or touch-ups brush application may be used when approved
by the Company Representative and only if proper agitation or mixing of
the primer is maintained to keep the heavy zinc filler in proper suspension.
1.8.2. Painting shall be done by workmen skilled in the craft of painting. Good
workmanship by skilled workmen is evidenced by the following features:
1.8.2.1. All crevices, such as around bolts, sharp angles, etc., are first
traced.
1.8.2.2. The entire surface shall be coated without attempt to "lay-off'
the paint in one direction, to leave a uniform film, free from
runs, sags and brush marks caused by not "feathering" or
blending one lap into another. Brushes should be springy and
not flabby.
1.8.2.3. Brushes or rollers shall not be permitted to become "seedy" from
skins.

adhere tightly to underlying metal, wood, or other paint film, or does not evidence a
normal workmanlike appearance shall be remedied or thoroughly removed and
replaced. When the final field coat does not have a uniform color and appearance
throughout, it shall be corrected by the use of whatever additional coats are
necessary. Freshly applied paint which has not yet set shall be removed with an
suitable solvent. Dried paint film shall be removed either by abrasive blasting or
scraping.
1.11. Protection Against Fire
At the completion of each day's work, all brushes, sprayers and other tools shall be

2.2. Preparation of Surfaces
2.2.1. Steel Surfaces
Throughout paint application, no paint shall be applied over a surface which
evidences of a loose or scaly condition. Every effort shall be made by
means of the most effective and practical methods to remove all loose mill
scale, rust, and dirt as well as other foreign substances which would be
deleterious to obtaining a film paint coating. Final preparation of steel
surfaces for painting shall be by abrasive blasting to a near -white metal in
accordance with NACE 2 or SSPC-SP10. Undesirable contamination which
will prevent proper hardening and adhesion of the paint film, such as oil,
grease, oily grime or moisture, shall be removed from surfaces prior to paint
application. Condensed moisture shall be avoided as specified in the
paragraph entitled "Weather Conditions and Dryness of Surface". Grease -
like contamination shall be removed with solvents applied with clean rags
in a manner which will remove and not simply dilute or spread out the oil
over a greater area. Particular attention shall be paid to cleaning of fillets,
bolted areas, and drilled holes where loose scale, rust or oil are most likely
to be present.
2.2.2. Previously Painted Surfaces
Where the surface to be painted has previously been painted and is in bad
condition due to cracking, peeling or chalking, the old paint shall be
removed to the satisfaction of the Company Representative.
2.3. Prime Coat (Steel Surfaces)
2.3.1. All piping, tanks, structures, etc., shall be abrasive blasted before painting.
The primer coat shall be applied immediately after abrasive blasting. In no
case will primer be applied later than the same day.
2.3.2. Piping, tanks, structures, etc., to be installed below grade shall be abrasive
blasted and coated in accordance with the Company approved below grade
coating specification.
2.3.3. The portion of piping and structure exposed to water spray, i.e. at cooling
towers, shall be abrasive blasted clean and coated as specified on the
Drawings.

2.3.4. When the material received is already primed and erection work is
completed, including all welding, straightening of bent material, etc., the
primer surface shall be restored to a serviceable condition acceptable to the
Company Representative by preparing the surface as specified and by
smoothing and touching up marred places with primer. Heads of bolts, field
welds and surrounding unpainted areas, and any other surfaces to be painted
which have not yet been painted, shall be painted with primer.
2.4. Field Coat (Steel)
2.4.1. When the prime coat is thoroughly dry, the first field coat of paint or
enamel may be applied. Field coats will not be required on the bearing
surfaces of bearing plates. These surfaces shall be coated as specified on
the Drawings.
2.4.2. When the first coat, including all touching up of marred places, has
thoroughly hardened, the finish field coat of paint or enamel may be
applied. After application of the finish field coat, the painted portion shall
present a uniform color appearance throughout.
3. THIN FILM COATED PIPE (WELD AREA AND HOLIDAY REPAIR)
3.1. General
Pipe shall be furnished to the Contractor with a yard -applied fusion bonded thin film
coating. The Contractor is cautioned to use care in handling the coated pipe in order
to prevent damage to the coating. All equipment which comes in contact with the
pipe shall be padded with rubber, Teflon, neoprene or equal. Skids and blocking
shall be padded with rubber, celotex, sand filled sacks or equal and be approved by
the Company Representative.
3.2. Coating
The Contractor shall coat the weld areas of the pipeline using heat curable,
thermosetting powdered epoxy coating with induction preheat, and fluidized flocked
application per approved specification, unless another method is specified in the
Project Scope. This coating may be applied by use of a high frequency induction

1. SCOPE
This section prescribes the minimum requirements for the design, transportation, mixing,
and placing of all concrete to be used in the Company concrete structures. Unless
otherwise indicated herein, all design and other work shall conform to and comply with
the latest revision of ACI Standard 318 Building Code Requirements for Reinforced
Concrete and ACI and ASTM specifications and recommendations references.
2. DEFINITIONS
2.1. "Alkali salt" is a soluble sulfate in water.
2.2. "Alkali soil" is soil which contains sulfates of magnesium, sodium, or carbonate
of sodium.
2.3. "Type I: Normal Portland Cement" is general purpose cement suitable for all
uses when the special properties of the other types are not required. It can be
used in construction of pavements, sidewalks, reinforced concrete buildings,
bridges, tanks, reservoirs, sewers, culverts, water pipe, masonry units, and soil -
cement mixtures. It should be used if no alkali soil conditions exist.
2.4. "Type II: Modified Portland Cement" is cement that has a lower heat of
hydration than Type I and generates heat at a slower rate. It also has improved
resistance to sulfate attack. It is intended for use in structures of considerable
size where cement of moderate heat of hardening will tend to minimize
temperature rise when concrete is placed in warm weather. In cold weather,
when the heat generated is advantageous, Type 1 is preferable. Type II cement is
also intended for places where added precaution against sulfate attack is
important, as in drainage structures where sulfate concentrations are higher than
normal, but are not unusually severe.
2.5. "Type III: High Early Strength Portland Cement" is cement used where high
strengths are desired to remove forms as soon as possible or to put the concrete
into service as quickly as possible and in cold weather construction to reduce the
period of protection against low temperatures.
2.6. "Type IV: Low -Heat Portland Cement" is a special cement for use where the
amount and rate of heat generated must be kept low. It is intended for use only in
large masses of concrete where temperature rise from heat generated is a critical
factor.

the test section during pressurization. Pressure shall be increased or decreased as
necessary during the hold period in order to maintain the test pressure.
10.4. Once the test pressure has been reached and the pressure stabilizes, deadweight
readings shall be recorded every 10 minutes during the first hour; every 15 minutes
thereafter until the test has been completed. Pressure, time, and volume of water
shall be recorded for any "bleeding -off' or re -pressuring. The contractor shall
pressurize the pipeline at a uniform rate, which can be maintained until test pressure
is reached, and at a reasonable rate which allows accurate pressure readings and
proper collection of data. Any abrupt changes or breaks on the charts should be
labeled as to the cause, at that point on the face of the chart. Pressure charts should
have the dead weight pressures noted at the beginning and end of the test.
11. HYDROSTATIC TEST
The contractor shall hydrostatically test the pipeline to the pressure indicated on the
Drawings or Project Scope, for the specified period; however, the Company reserves the
right to require the Contractor to maintain pressure beyond the specified period, if the
pressure has not stabilized due to temperature or it cannot be determined if there is a leak
within the test section. The Contractor shall furnish the Company the quantity (gallons or
strokes) of water used for each repressure. The volumes of water added or removed to
control test pressures shall be metered and recorded. Contractor shall locate and repair any
leaks or failures which occur and the pressure test shall be restarted until a continuous 8 -
hour test period is achieved and recorded.

1. OVERVIEW
1.1. Introduction
The following specifications apply to pipeline construction that parallels overhead
high voltage electric transmission lines in the same right-of-way or in close
proximity thereto.
These specifications are not intended to be all inclusive, but represent minimum
requirements only. These specifications are intended to minimize the hazard of
electrical shock to personnel from induced voltages or fault currents that might
appear on the pipe during the progress of construction. They are designed to remind
the Contractor of the potential hazards, which may be associated with pipeline
construction in the vicinity of induced voltages, fault current, and contact to high
voltage electric transmission lines. Precautions in addition to those listed below
may be necessary as conditions warrant. All personnel and material associated with
this procedure will be provided by the Contractor.
The Contractor should review the project and initiate additional requirements as
he/she deems necessary to ensure safety of persons and property affected thereby.
1.2. Guidelines
1.2.1. Piping parallel to, crossing, or in proximity of electric power transmission
lines are subject to electrostatic and electromagnetic induced voltages and
currents. The Contractor is required to provide trained electrical safety
inspectors to supervise the necessary mitigating procedures associated
with electrical safety on the pipeline. The Contractor and his/her
personnel should be aware of safety requirements when construction
crosses or parallels electrical power lines.
1.2.2. Department of Transportation regulation 49 CFR Ch. states:
"Where a pipeline is located in close proximity to electrical transmission
tower footings, ground cables or counterpoise, or in other areas where fault
currents or unusual risk of lightning may be anticipated, it must be provided
with protection against damage due to fault currents or lightning, and
protective measures must also be taken at insulating devices."
1.2.3. The principal limiting factors of construction are the minimum sag of the
wires and the distance from the conductors that must be maintained by

equipment operators to ensure against electrical shock resulting from
induced voltage. In the latter case, the Occupational Safety and Health
Administration (29 CFR Ch. XVII) dictates:
Except where electrical distribution and transmission lines have been
deenergized and visibly grounded at point of work or where insulating
barriers, not a part of or an attachment to the equipment or machinery, have
been erected to prevent physical contact with the lines, equipment or
machines shall be operated proximate to power lines only in accordance
with the following:
1.2.3.1. For lines rated 50 kV., or below, minimum clearance between
the lines and any part of the crane of load shall be 10 ft.
1.2.3.2. For lines rated over 50 kV., minimum clearance between the
lines and any part of the crane or load shall be 10 11. plus 0.4 in.
for each 1 kV. over 50 kV., or twice the Iength of the line
insulator, but never less than 10 ft.
1.2.3.3. In transit with no load and boom lowered, the equipment
clearance shall be a minimum of 4 ft. for voltages less than 50
kV., and 10 ft. for voltages over 50 kV., up to and including
345 kV., and 16 ft. for voltages up to and including 750 kV.
The Contractor shall adhere to these regulations at all times. In addition,
the minimum clearance for lines 750 to 1,000 kV shall be 20 ft. These
guidelines are for ideal weather conditions, and the clearances shall be
greater under more adverse weather conditions.
2. ELECTRICAL SAFETY INSPECTOR
2.1. Guidelines
The electrical safety inspector is the responsible person in charge of electrical safety
during construction of the pipeline.
The Contractor with approval of the Company shall supply this inspector.
2.2. Requirements
2.2.1. The Electrical Safety Inspector shall:

a) have extensive knowledge of National and State codes for electrical
safety;
b) be fully aware of proper grounding procedures and the dangers
associated with inductive and conductive coupling, lightning, fault
current, power arc, etc. on above and below ground structures; and
c) know the intrinsic hazards of the construction equipment being used and
the safe distances from overhead conductors required.
2.2.2. The Electrical Safety Inspector shall:
a) furnish the instrumentation required to monitor voltage levels, and
ascertain vehicle instrumentation, equipment, and authority required to
ensure safe working conditions;
b) communicate at least daily with the power company dispatcher
controlling the involved electric lines;
c) have stop task authority;
d) obtain weather information daily from the local weather office;
e) have the authority to inspect all pipeline and construction equipment
grounding procedures; and
f) have a strong background in electrical distribution and grounding so that
these duties can be fully understood.
3. WORK STOPPAGES
3.1. Introduction
Further reduction of the possibility of electrical hazards can be achieved if work on
the pipeline is suspended during periods of severe weather, or when adjacent power
lines are being energized or de -energized.
3.2. Guidelines
Since temporary grounding is not intended to safely mitigate voltages arising from
lightning or power line faults, it may be necessary to halt all pipeline construction
during inclement weather conditions.

4.3.2. Insulated Rubber Sheet
4.4. Procedure
If any metallic structures are exposed, check to see if they are coated. In the event
that the structure is coated, the coating should prevent contact with any voltages that
exist between the pipe and the foreign structure, although (if deemed necessary by
the Electrical Safety Inspector) the structure should regardless be tested for high
voltages. If the structure is not coated, then follow these steps:
4.4.1. Measure AC voltage(s) on the foreign structure
4.4.2. Record value(s) on a data sheet (Figure 1)
4.4.3. Pipe to foreign structure voltage > 15 volts?
a) YES - Wrap the structure with an insulated rubber sheet, similar to what
electrical linesmen use when working on live conductors. If this does
not prevent the voltage hazard, Grounding or Bonding procedures may
be required. See page 15 for Grounding procedures, or page 18 for
Bonding procedures.
b) NO - No special procedures are required.
The pipe shall not be grounded or bonded to a foreign structure without permission
of the owner of the foreign structure. If the owner will not allow direct bonding or
grounding, other provisions shall be made.
5. POTENTIAL MEASUREMENTS OF PIPE
5.1. Introduction
The pipeline to ground voltage of any string of pipe, exposed to contact by
personnel, shall be measured periodically using a calibrated voltmeter of suitable
range and high impedance (approved by Electrical Safety Inspector).

way, attach a chain to the vehicle's frame of suitable length to maintain
contact with the ground.
8.3.2. Park vehicles no closer than 200 ft. from the right-of-way unless the
vehicle is grounded.
Each fuel truck shall be equipped with a cable assembly capable of
completing an electrical bond between the truck and any piece of equipment
to be fueled. Fuel trucks and equipment must be grounded with a ground
rod prior to grounding between them. It is required that this bond be made
each and every time, prior to any part of refueling operations are completed.
Care shall be taken where the cable attachments are made so that good
electrical continuity is established.
Rubber tired vehicles shall not be refueled on the electric power right-of-
way unless (1) the vehicle is electrically bonded to the fueling
facility/vehicle prior to commencement of the refueling operation, and (2)
the refueling vehicle is grounded to earth.
Rubber tired equipment parked for any appreciable time on a power line
right-of-way may collect a considerable charge of static electricity. Efforts
should be made to park such vehicles away from overhead lines. Vehicles
should be parked no closer than 100 ft. from the base of electric line towers.

All tired vehicles, if parked on the right-of-way for over 5 hours, must be
grounded with at least a % in diameter ground rod that is driven or screwed
to a depth of at least 4 ft. All vehicles which might be parked on the right-
of-way for 5 hours or more at a time shall be equipped with a 1/2 in. copper
ground rod and connecting cable assembly. Cable shall be at least No. 8
AWG and have insulated clips capable of completing an electrical bond
between the ground rod and the automobile. Each time an automobile is
parked on the power line right-of-way, the ground rod shall be pushed as far
as possible into the ground, and an electrical connection made between the
rod and the automobile. This bond shall remain as long as the car is parked
on the power line right-of-way. Signs shall be posted for "authorized
vehicles only."
If rubber tired equipment is required to move about, then a short chain can
be dragged behind the equipment for grounding in lieu of using a ground
rod as stated above. The chain shall be heavy duty with at Least 1'/2 in.
links. The Contractor is to provide the Company's vehicles with the
equipment for grounding.
At all times during construction, care must be exercised to assure that
booms and cables are no closer than 10 ft. from overhead power lines.
Minimum mid -span height between power line towers can range anywhere
between 20 and 25 ft. Usually this height is greater, but in some cases the
power lines may sag to this low, or even Iower. Height should never be
taken for granted, but should be investigated in each case. Check with the
local power company for vehicle clearance. Consideration must also be
given to the possibilities of broken cables whiplashing close to power lines.
Each piece of equipment shall be positioned so that should this occur, the
cable would not come closer than 25 ft. from a power line.
9. CONNECTING & DISCONNECTING GROUNDING FACILITIES

9.4.2. Connect pipe end grounding clamp to the pipe. WARNING: there is a
possibility that a voltage will occur on the pipe that may be a safety
problem even while the operator is connecting the pipe end grounding
clamp to the pipe. Due to this risk, the operator should use insulating
tools and gloves, and should avoid standing in wet ground. Any other
special precautions deemed necessary should also be followed.
9.4.3. Connect grounding cable to the grounding facility/rod.
9.4.4. Connect grounding cable to the pipe end grounding clamp.
9.4.5. Cables used for temporary grounding attachments shall have good
mechanical strength as well as high conductivity. The cable shall be
single conductor AWG No. 3, 1715 -strand welding cable or equivalent.
Cable attachments to temporary grounding systems shall be made using a
method that assures good electrical contact with the pipe metal, and
which applies firm pressure. The method of attachment should have a
current carrying capacity of at least 200 amperes. Connections may also
be made by the Thermite weld process, but under no circumstances
should there ever be any arc welding of temporary clamps.
When grounding joints or strings of pipe, the ground rod shall be driven,
and the connection between the rod and the ground cable made first. The
connection between pipe and ground cable may then be made. Removal of
all cables shall be in reverse order, that is, the cable should be disconnected
from the pipe first. All grounding attachments or removals will be made by

Each string of welded pipe that is between loose ends shall temporarily be
grounded to a ground rod at least 1/2 in. in diameter, and which is driven to a
depth of at least 4 ft. Any string of continuously welded pipe in excess of
2,000 ft. shall be grounded at least twice, and strings of pipe should be
limited to 3,000 ft. long. These temporary grounds shall be maintained until
the sections are tied into portions of line that have permanently been
grounded with zinc wire or magnesium anodes and backfilled.
It is acceptable to use bare road casing for additional grounding during
construction. This may be done by attaching a bond cable between any
exposed metallic surface of the pipeline and the bare casing. Any bonds
made for this purpose must be removed before the backfilling operation.
It is acceptable to use straight polarity welding for stringer bead should the
electromagnetic field produced by the power lines cause magnetization of
the pipe.
When the pipeline no longer requires grounding, the grounding system may
be disconnected.

1.0 INTRODUCTION
This Stormwater Management Plan (SWMP) identifies measures to be taken on the South
Parachute Loop Pipeline Project (project) to meet requirements set forth by Colorado
Department of Public Health and Environment (CDPHE) Division of Water Quality Control, for
controlling stormwater discharges associated with construction activity.
Measures identified in this plan apply to ETC Canyon Pipeline, LLC (ETC) and the contractor(s)
(Contractor) it employs to construct the pipeline. Measures in this plan pertain to the entire
project, which is defined as the right-of-way (ROW), temporary use areas, access roads, and all
other areas utilized during construction activities.
This SWMP describes procedures to minimize the potential for erosion, sedimentation, and the
discharge of pollutants, both on and off ROW, by the use of proper construction techniques and
the adoption of appropriate Best Management Practices (BMPs). These BMPs will be
implemented and maintained during all active construction activities and maintained until the
terms and conditions of the associated stormwater permits have been fulfilled_
This plan is required, by CDPHE Division of Water Quality, to be available on-site during active
construction and during site inspections.
ETC currently holds two stormwater discharge permits which cover the geographical area in
which construction will take place. The permit numbers and expiration dates are listed below:
Certification Number
Expiration Date
COR038333
06/10/2010
COR038335
06/10/2010
These two permits will be modified to reflect the additional amount of acreage disturbed by the
project.
2.0 SITE DESCRIPTION
2.1 Nature of Construction Activities
The South Parachute Loop Pipeline Project involves installing 13.9 miles of natural gas pipeline.
The pipeline will be constructed of 24 inch steel pipe, which will be buried to an average depth
of 5 to 6 feet.
The purpose of this project is to increase natural gas transportation capacities within the area of
the proposed project. The current transportation system is at full capacity at approximately 20
million cubic feet per day (cf/d). This project will create an additional 240 million cf/d capacity,
which will transport anticipated, increased natural gas production in this area.

2.2 Sequence of Major Activities
Construction is planned to begin in the spring of 2008 and is anticipated to be completed by late
summer or early fall of 2008. The project will utilize standard linear pipeline construction
techniques. These techniques will sequence as follows:
1.) Clearing —
2.) Grading --
As necessary for safety and construction feasibility, vegetation, rocks, and
debris will be removed or relocated to either outer edge of the ROW.
Clearing activities will prepare the ROW for the grading process to follow.
During grading activities, topsoil is removed, as required, and is
segregated and stored on the ROW for later redistribution. Grading
activities will also involve leveling the ROW where slopes present an
unsafe construction environment.
3.) Trenching — Trenching involves excavation of the trench used to bury the pipeline.
4.) Stringing —
5.) Welding —
6.) Lowering —
Sections of pipe will be strung in Iinear fashion after the ROW has been
prepared by clearing and grading activities.
During welding activities, the pipe sections will be welded, coated, and
possibly x-rayed to allow the pipe to be lowered into the trench.
Welded sections of pipe are lowered into the trench.
7.) Backfill — After the pipe is lowered into the trench, the subsoil is returned to the
trench to cover the pipe.
8.) Cleanup --
9.) Restoration —
10.) Tie -In —
During the cleanup operations, contours are re-established by placing
subsoil back into its original location and topsoil is redistributed over the
entire disturbed ROW.
Restoration involves reseeding, mulching, and spreading removed
vegetation and rock over the ROW. During restoration, the permanent
BMPs will also be installed.
Tie-ins will occur over the entire length of the project where initial
construction efforts were unable to continue building linear pipeline (road
crossings, wetlands, etc.). Tie-in locations will utilize the nine processes
described above.
4
2.3 Acreage Disturbed by Construction Activities
The project will utilize a 60 foot wide construction right-of-way over the entire length of the 13.9
mile project. The maximum amount of soil disturbance associated with ROW construction is
101 acres. The project will also utilize three, two -acre temporary use areas which increases the
total acres of possible disturbance to 107 acres.
The project is designed to disturb the minimal amount of acreage within the construction ROW,
while maintaining a safe and effective work environment. The actual amount of disturbed
acreage is anticipated to be notably less than the maximum amount of potential soil disturbance.
2.4 Soil Description and Potential for Erosion
Surface soils range from sandy to clay soil types. Sections of the project contain a significant
amount of rock in the surface layer. The pipeline's route generally follows flat terrain with
slopes of less than 3%. However, the project will cross several drainages where slopes will
approach 100%. The post -construction runoff coefficient will be between 0.20 and 0.79,
depending on slopes, soil types, and soil stabilization activities. Pre -construction runoff
coefficients are estimated to be lower on average, but not significantly different than post -
construction coefficients.
2.5 Description of Existing Vegetation
The project primarily follows flat or rolling tops of mesas, with the elevation ranging from about
5,500 feet to near 7,000 feet. Vegetation on mesa tops range from grass, shrub, and woodland
species to agricultural/pasture vegetation. Steeper drainages are characterized by more shrub and
woodland species of vegetation.
The percentage of ground cover ranges greatly from 0% to 100%. Typical ground cover over the
length of the project is 40%-75%.
2.6 Potential Pollutant Sources
The four primary sources of potential pollutants associated with construction of the project are
listed below. These potential pollution sources will be possible over the entire length of the
project.
• Vehicles & Equipment — Fuel, hydraulic and motor oil, lubricants, other greases
• Painting & Coating — Paint, solvents, coating materials
• Herbicide Treatment — Herbicides, buffers, and drift- control agents
• Construction Activities — Loose soil, dust
The release of these potential pollutants during construction or storage will be minimized by
adhering to the Hazardous Materials Management and Spill Prevention and Countermeasure
5
Plan, Soil Conservation, Sedimentation, and Erosion Control Plan, Fugitive Dust Control Plan,
and the Reclamation Plan.
2.7 Non-Stormwater Discharges
The project may require non-stormwater discharge in the form of trench dewatering. In the event
a trench is filled with ground water, or after a storm event, the water will be pumped out of the
trench to facilitate construction efforts. Discharge from trench dewatering will be directed to a
well -vegetated area or other measures will be taken to prevent the discharge from scouring the
land. Discharge of heavily silt -laden water will be minimized by controlling the location of the
pump's intake and/or discharging through a sediment bag or functionally equivalent device.
2.8 Receiving Waters
The project is located within the Colorado River Basin and the Colorado River will be the
ultimate receiving water for all waterbodies crossed by the project. The project crosses 3
perennial waterbodies (Cache Creek, Cottonwood Creek, Battlement Creek) and 31 intermittent
waterbodies.
3.0 SITE MAP
The South Parachute Loop Pipeline Project resides entirely in Garfield County, Colorado.
The pipeline begins approximately 9 miles southwest of Rifle, Colorado at Township 7S, Range
94W, Section 9 and terminates approximately 5 miles south of Parachute Colorado in Township
7S, Range 96W, Section 36.
Maps are included as Attachment 1 and illustrate the location of the project boundaries and
associated ground disturbance, location of anticipated BMPs, and the location of waterbodies.
ETC is currently in the process of securing three, two -acre temporary use areas from private land
owners. The locations of these temporary use areas cannot be located on the maps at this time.
4.0 STORMWATER MANAGEMENT CONTROLS
4.1 SWMP Administrator
ETC Canyon Pipeline, LLC will employ contractors to provide SWMP administration over the
project. Aspen Environmental Field Services, LLC is responsible for developing the SWMP.
The Environmental Inspector and/or Stormwater Inspector will be responsible for implementing,
maintaining, and revising the SWMP during active construction. The Stormwater Inspector will
be responsible for maintaining and revising the SWMP after construction is complete. The
SWMP will be maintained until final restoration is complete and requirements of any associated
permits have been fulfilled.

4.3 Best Management Practices for Stormwater Pollution Prevention
4.3.1 Structural Practices for Erosion and Sediment Control
Structural practices employed by this project will represent the primary control measures in
preventing or minimizing stormwater discharges of sediment and erosion control. The
anticipated Iocations of structural erosion and sediment control measures are located in the maps
included as Attachment 1. The project parallels an existing natural gas ROW. The approach
taken for sediment and erosion control by use of structural measures, will be to extend control
measures currently in place on the existing, paralleling ROW to include the new disturbance
from this project.
The project will use waterbars, sediment basins, straw waddles, check dams, rock aprons, and
culverts to perform the structural erosion and sediment control. Other devices may be utilized if
found appropriate during the time of construction or during follow-up maintenance.
4.3.2 Non -Structural Practices for Erosion and Sediment Control
Non-structural erosion and sediment control practices will be used in conjunction with structural
practices to deliver effective stormwater erosion and sediment control. Removal of existing
vegetation will be minimized during clearing and grading activities, with emphasis being placed
on preserving existing trees and other mature vegetation. The removal of such vegetation will be
limited to only that vegetation that must be removed to install the pipeline or provide a safe
working environment.
Planting of temporary and permanent vegetation will be utilized in conjunction with mulching,
geotextile fabrics and slope roughing to perform the majority of soil stabilization. These non-
structural practices will be employed over the entire length of the project as able and/or required
by the associated landowner.
4.3.3 Phased BMP Implementation
The application of BMPs will be used over the entire course of the project construction and
maintenance activities. During active construction, sediment, erosion, and pollutant discharges
will be addressed primarily by the installation of temporary waterbars, straw waddles, sediment
fence, and adhering to the Hazardous Materials Management and Spill Prevention and
Countermeasure Plan.
During final restoration efforts, several structural and non-structural practices will be deployed.
These include, but are not limited to, seeding, mulching, geotextile fabric, slope roughing,
permanent waterbars, sediment traps and other structural and non-structural practices. Practices
deployed during final restoration will also be utilized, as needed, during the maintenance period
of the project to provided continued soil stabilization and sediment control.
4.3.4 Materials Handling and Spill Prevention
Material handling and spill prevention are addressed in detail in the Hazardous Materials
Management and Spill Prevention and Countermeasure Plan. Project compliance will be
handled by adhering to this plan. Spill prevention will be attained by properly using secondary
containment systems and storing hazardous materials away from sensitive areas. Immediate
countermeasures will be taken in the event of a hazardous material spill.
4.3.5 Dedicated Concrete or Asphalt Batch Plants
This project will not be utilizing dedicated concrete or asphalt batch plants.
4.3.6 Vehicle Tracking Control
It is the Contractor's responsibility to install vehicle tracking control measures and to remove
sediment once tracking has occurred. The intersections of all access roads and the ROW that
intersect paved roads will be cleared, as necessary, of vehicle tracked sediment at the end of each
work day. Severe vehicle tracking that posses a safety concern will be immediately removed.
The Contractor will utilize street sweepers, scraping equipment, hand tools, or pressurized water
to remove sediment tracked onto paved roads.
The Contractor may install gravel approaches to paved roads to assist in controlling vehicle
tracking. Geotextile or similar fabric will be placed beneath gravel to promote easy removal
when the approach is no longer needed. The Environmental Inspector may also direct the
installation of gravel approaches as he/she sees fit.

4.3.7 Waste Management and Disposal, Including Concrete Washout
Minimal concrete is anticipated to be used on this project. Concrete may be used in the
installation of mainline valves, pig launchers, or other assembly directly related to the pipeline.
During these types of concrete applications, the Contractor will ensure that concrete washout
water is discharged into the associated, exposed trench or other nearby like areas. The concrete
washout water will be discharged onto subsoil which is below surrounding grade to prevent
stormwater discharge of the concrete.
Refuse dumpsters, recycling bins, portable toilets, or any other containers storing liquid or solid
waste will only be utilized under the following guidelines:
• Containers will be located a minimum of 100 feet away from sensitive areas
• Containers will be emptied at an appropriate location, or hauled off by an appropriate company
• Containers will be emptied on a regular basis to prevent overflow
Contractor shall enforce good housekeeping skills on entire project staff. Dumping of any
debris, regardless of size or type, onto the project will not be allowed.
4.3.8 Groundwater and Stormwater Dewatering
Groundwater and stormwater dewatering will only occur if groundwater or stormwater presents
an obstacle for construction. Dewatering will only occur in the form of trench dewatering and
wells will not be used to lower groundwater levels. An Industrial Wastewater Discharge Permit
is being obtained by the project to permit discharging of groundwater not otherwise covered by
the stormwater permit.
5.0 FINAL STABILIZATION AND LONG-TERM STORMWATER
MANAGEMENT
5.1 Final Stabilization
Final stabilization of the project will be considered during all phases of construction activity. All
things being equal, choices made during construction will favor those options that will enhance
the final stabilization process. Clearing and grading activities will give extra attention to the
final stabilization process.
During clearing and grading activities, the minimum amount of soil and vegetation will be
disturbed while providing a safe and efficient work area. In particular, the removal of trees will
be limited to only those that must absolutely be removed. Where feasible, root systems will be
left in place and the herbaceous vegetative crown will be maintained where grading of the ROW
and extra work spaces is not necessary. Vegetation removed during clearing activities will be
placed on the edge of the ROW to be redistributed after final grading has occurred.
9
Only those portions of the ROW that require grading will have topsoil removed and stored on the
edge of the ROW to be redistributed during cleanup activities. Where topsoil is graded, the
entire topsoil layer, up to 12", will be stripped unless otherwise stipulated by the individual
landowner.
Cut and fill technique will be utilized only where slopes present a safety concern for construction
activities to follow.
By minimizing vegetation and soil disturbance and protecting the topsoil resource, vegetation
will be able to be effectively restored over the entire ROW.
Final stabilization will be achieved by the proper placement and installation of BMPs, planting
the correct seed and/or plants, during the correct season, for the applicable soil type, and
installing additional soil stabilizer, such as crimped mulch, where necessary.
The location and type of BMPs are outlined in this plan or will be identified in the field by the
Environmental Inspector. The proper selection of seed and/or plants will be identified by the
landowner or by the recommendations of the National Resources Conservation Service. Soil
stabilizers will be installed at the direction of the Environmental Inspector.
5.2 Long -Term Stormwater Management
Oversight of long-term stormwater management will be the responsibility of the Stormwater
Inspector assigned to the project after construction is complete. The Stormwater Inspector will
conduct monthly inspections of BMPs and note areas of erosion or poor vegetation return.
Maintenance requests will be made by the inspector to ETC or assigned contractor to make
necessary repairs as needed.
6.0 INSPECTION AND MAINTENANCE
6.1 Inspection
The project's Environmental Inspector and/or Stormwater Inspector will be responsible for
performing inspections of alI project BMPs and completing the associated inspection reports.
6.1.1 Construction
In areas of active construction, BMPs will be inspected on a daily basis. Areas of active
construction, includes those portions of the project being used to access construction sites and
temporary use areas with associated activity. BMPs located in areas without activity must be
inspected every 14 days.
All BMPs will be inspected within 24 hours of a 0.5 inch, or Beater, precipitation event. If
ROW conditions do not allow for timely, post -storm inspection of BMPs, the inspection will take
10
place within 72 hours and prior to the re -commencing of construction activities. Any such
delays in inspection of BMPs must be documented in the inspection report.
6.1.2 Post -Construction
Portions of the project where active construction is complete, BMP inspection intervals may be
reduced to once a month as long as the following conditions exist:
• All ground disturbance construction activities are complete
• All activities identified in the SWMP for final restoration are complete (seeding not required)
• SWMP has been amended to indicate areas under reduced inspection intervals
BMPs identified as being insufficient will continue to be properly maintained and/or reinstalled
as necessary.
6.1.3 Winter Inspection Exclusions
Routine 14 -day, monthly, and post -storm inspections are not required for those areas of the
ROW where there is no active construction, snow cover exists over the entire ROW, and melting
conditions are not present. This exclusion should be properly documented in the inspection
report.
6.2 Maintenance
The Contractor will be responsible for correctly installing erosion and sediment control
measures. The Contractor is also responsible for properly maintaining these sites after installed.
Maintenance of BMPs will be performed by the Contractor, as needed, within 24 hours of
discovery or notification, or as soon as ROW conditions will allow.
